#1 – PhenQ

phenQ pills

Many were surprised how this fat burner sparkled in people eyes with the major increase in its market share in weight loss industry in the UK.

We the believe the secret of PhenQ relays on the α-LACYS RESET® technology.

Triggering different strings in human physiology to accelerate metabolism without the traditional way that comes with side-effects.

The synergistic part the boosted PhenQ to #1 is simply, adding Capsimax™ from OmniActive Health Technologies.

This made a significant impact on plasma free-fatty acids increased after ingestion at two hours (pre-exercise) and one-minute post-exercise compared to placebo.

Which means? It means these higher levels of free fatty acid levels and glycerol indicate lipolytic activity due to the capsaicinoids present in Capsimax. and laster targeted approach to burn fat, literally.


Scientific proven results:

When compared to a placebo, people who took PhenQ (per month):

  • Lost 3.44% body weight

#2 – Phen375


The product manufacturer a global-renowned supplement company, Shippitsa ltd. Aims to fill the vast gap in the weight loss market with a working fat burner, after the Phentermine Ban.

This fat burner works significantly on enhancing the thermogenesis and lipolysis effect of the body.

It’s secret is instead of providing directly epinephrine, norepinephrine (like banned phentermine) it creates the environment for the body to increase its production of these hormones.

It is cleverly using the body’s metabolism to aid itself without an external foreign factor. The downside might be it has caffeine to boost the metabolism.

Scientifically proven results:

If one of the ingredients stated in Phen375 not included. It wouldn’t provide the desired results.

However, there were some major tests done on Bitter Orange (one of its ingredients called Citrus Aurantium) is a close relative of, and acts in the body like pseudoephedrine (the main component in methamphetamine) this ingredient triggers the body ephedrine.

Also, Chromium Picolinate (in Phen375 ingredients) significantly help to reduce the accumulation of abdominal fat. Read more on our indepth review of Phen375

Side-effects discussed:

Some reported side-effects because of bitter orange poses some of the same serious health risks because of its stimulant-like effects. Among the many chemicals in bitter orange are synephrine and octopamine — chemicals similar to those in ephedra. These chemicals may speed up your heart rate and raise your blood pressure. For that, it is extremely contraindicated with anyone dealing with general cardiac complications or hypertensive patients. Also under age 18 or pregnant and nursing mothers are also advised not to use the product.

3. Zotrim (Known as the Herbal Fat Burner)

This pill has it’s herbal essence among other fat burners. The reason for that, it combines Damiana leaf extract with Guarana seed and Yerba Mate.

The combination is believed to produce a thermogenic effect and used in Chinese medicine to help delay gastric emptying which appears to help keep patients feel full and eat fewer calories as a result.

This fat burner designed for the ones who prefer to have 100% herbal treatment when it comes to weight loss.

It might not be much efficient when compared with the first two (Phen375 and PhenQ) but it works at a slow pace.

4. Ketonebalance Duo (Green Coffee + Raspberry Ketones)

To make the long story short. What makes KetoneBalance Duo unique, is that it combines two major fat burners into one. Raspberry ketones and Green coffee.

This fat burner is a new dietary supplement developed and distributed by Evolution Slimming, an acclaimed, UK-based dietary supplement company.

What got this pill to the #4 in the UK is simply targets the ones who are eager to lose fat and not much on the weight loss.

Plus it’s considered overall cheap compared to its expensive ingredients and among other fat burners.

Scientifically proven results:

The secret recipe behind the scenes can be spoiled when I mention high amounts of chlorogenic acid. If you take the chlorogenic acid on a daily basis you will be able to reduce your body fat by up to 30 per cent.

This powerful ingredient found in Green Coffee. However, when it’s blended in a well-proportioned ration with Raspberry Ketones extract.

It leads to a significant increase in the metabolic rate but also enhances the effect of chlorogenic acid on the breakdown of body fats. Read more on our indepth review of Ketonebalance

Side-effects discussed:

If you hate caffeine or anything related to coffee. This pill is not for you. Because of 200mg of green coffee + 100 mg of green tea + 100 mg of Guarana … The 3 ingredients have caffeine. It might not be in its extract form, which means more beneficial than the caffeine in the coffee. Still it’s caffeine. Also, many doctors advice to no exceed than 300 mg of caffeine per day. This means for you the amount of dose of caffeine you take through coffee must be decreased.

Money Back Guarantee

Customers are offered a 30-day money back guarantee.

5. Nuratrim (Kim Kardishian pill)

I would say this is one of the lucky fat burners in the UK. It doesn’t have a distinct feature among other OTC fat burners.

But thanks to the endorsement Kim Karishian and other celebs. Nuratrim’s sales sky-rocketed in all Europe and USA and not just UK.

However the main unique ingredients that provides that actual results were Glucomannan and Capsicum.

Scientific proven results:

The main weapon that used by Nuratrim is Glucomannan. Glucomannan alone can absorb up to 200 times its weight in water.

Helps you to feel fuller quicker so that you eat less. It does this by swelling in your stomach by absorbing up to 200 times its weight in water.

It also has Capsicum which is found in (Phen375 and PhenQ) and it provides good value in boosting metabolism. You can read more on our indepth review on Nuratrim

Side-effects discussed:

The Nuratrim  website claims that there are no side effects to the product. However, there have been reports dotted around the website.

that there may be some diarrhoea and stomach cramp symptoms associated with the taking of Nuratrim in the first week and some got tolerance on the end of the second week.

Nuratrim_UK_User Amazon Reviews

As you can see there is huge diversity with Nuratrim, it worked for many but also didn’t work for the other many. So you have to understand it might not be for you. And you would know, well never know until you try. That’s the point.

Our Verdict:

We believe that a fat burner will not solve your weight loss issue unless you start to take real action towards your diet and lifestyle. Cutting on junk foods or sodas. Jogging 30 mins per day at a minimum and having the mindset of consistency. Then and only then these previous fat burners work and enhance your performance to a tangible level.
